OIL BURNER.

Application filed January 11, 1924.. Serial N'o. 685,510

To all whom it may concern:

Be it known that I, CARL BUBERL, a citizen of the country of Austria and resident of the city of Detroit, county of Wayne, and State of Michigan, have invented certain new and useful Improvements in Oil Burners, of which the following is a specification.

My invention relates to an oil burner of the type utilizing a wick from which the flame extends and has'for its object the construction of a simple and economical device designed to give the utmost efficiency.

With these and other ob ects in view, my invention consists in the arrangement, combination and construction of the various parts of my improved device as described in the specification, claimed in my claims and shown in the accompanying drawings in Fig. 2.

I have shown a base having a plurality i of apertured knobs or projections 6 thereon into which rods or standards 7 may extendand be secured by means of set screws The standards 7 are screw-threadedon their upper ends as at 9 and nuts 10 are screwedthereon at a suflicieut distance to permit the placing of a casting 11 on the top thereof. A member 12 may be placed on the top of the ring 13 on the casting 11 or casted integrally therewith, as desired.

A ring 14 having a plurality of downwardly extending portions 15-separated by openings-16. is provided with a ledge 1 adapted to seat onv a ledge 18 provided on the inner periphery of the casting 11.

An apertured knob 19 is also provided on the base 5 into which the rod or standard 20 is placed and secured by means of a set screw 21. A pin 22 is disposed thru the rod 20 adjacent its upper end and an apertured member 23 is disposed over the rod 20 and secured in place by the pin 22. The upper face of the'member 23 is of tapered formation and a tapered member 24 is also disposed over the rod 20 and intothe hollow of the tapered portion, of the member'23, thus securin it against displacement.

A I0 25 having an extended outer end 26 thereon and a forked inner end 27 is pivoted at 28 to an ear 29 provided on the base 5.

The forked end 27 of the rod 25 is disposed around the rod 20 and an apertured ring 30 havingupwardly extending legs 31 is positioned over the rod 20 and against the forked end 27 of the rod 25. The legs 31 support a channeled ring 32 into-which circu ar plates 33 and 34 are inserted and secured by screws 35 and 36 respectively. The circular plates 33 are provided on their outer faces with a plurality of extending faces'37 of substantially thesame formation and size as the extensions 15 on the ring 14.

Disposed between the plates. 33 and 34 is a circular tank or compartment 38 in which a wick 39 is positioned upon a standard 40.

Additional knobs 41 are provided in the base 5 into which rods 42 and 43 are extended and secured. by means of set screws 44 and 45 respectively. 'The rod 42 and another similar rod, not shown, extend upwardly thru the channeled ring 32 and fuel thereto from the fuel line 45. The base' 5'is provided with ears 47 into which set screws 52 are placed so that the base may be levelled on the bottom of the furnace.

The casting 11 is of such size as to substanthe furnace wall.

In. the practical operation of my improved burner, it will appear therefore that fuel being contained in the chamber or tank 38 will be carried outwardly thru the wick 39 so as to make a continuous circle of flame around the exposed portion of the wick 39. The course of the flame will be thru the opening between the portion 48 on themember 23 and the central opening in the member 12 and thence against the tapered member 24 with the result that the fuel will be entirely'burned before it has yond any of the before lnentione members and before reaching the boiler of the furnace, thus preventing the collection of soot because of unburned portions of-fuel being directed against a cold body such as a boiler.

For regulation of the flame, movement of the lever 25 upwardly and downwardly will cause the plates 33 and 34 to respectively expose less or more of the wick 39. Amount of the flame present will, of course, depend upon the amount of wick which is exposed. The extension 26 of the lever 25 may be connected to any suitable thermostat or other automatic regulator so as to automatically control the amount of flame according to the heat required.

Air for mixing with the fuel will be conducted thru the passageway between the portion 49 of the member 23 and the "upper portion of the plate 34. It will be noted that the portion 49 of the member 23, being. tapered, will admit the passage of more air when a greater portion of the wick is exnteed than when a lesser portion 'of the wick is exposed. Further air will be passed upwardly for mixture with the fuel between the ring 14 and the plate 33. The amount of air which passes at this junction is controlled by movement of the ring 14 so as to have the portions 15 thereof co-ordinate with the projections 37 on the plate 33 so as to control the sizes of the open spaces 16 or to entirely close them. Thus a fixed amount of air may pass between the ring 14 and the plate 33, as conditions suit, and a variable amount of air may pass between the plate 34 and that portion 49 of the member 23 according to the amount of fuel being burned. V

I have shown a pipe 50 extended into the channeled portion of the member 32, which is adapted to act as an over-flow pipe to carry any fuel which may over-flow from the tank 38 outside the furnace into any suitable container. I employ, however, a suitable fuel control outside the furnace intended to regulate the amount of fuel fed to the tank.

I have also shown a projection 51 on the wick 39 which extends thru an aperture provided therefor in the member 12. The projection 51 is of thesame material as the wick and may be made either integrally therewith or separately cast. .Its function is to act as a pilot light for the burner when the wick is almost or entirely closed off and it may be located elsewhere than on top of the wick, so long as it is so placed that the draft passing thru the burner will direct its flame against the wick when it becomes exposed.

It will be seen, from the above description, that the construction of the burner is simple and such as will permit of ready assembly or disassembly and further, that it is such as to obtain the utmost efficiency because of the construction of the combustion elements and regulating devices.

It is obvious that various changes may be made in the arrangement, combination and construction of the various parts of my improved device without departing from the spirit thereof, and it is my intention to cover by my claims such changes as may be reasonably included within the scope thereof.

What I claim is:

1. A device of the class described, comprising a wick burner, a movable member adapted to expose varying amounts of said wick in a combustion chamber, an air passage between said movable member and a fixed member, at least one of said members being at an angle to the other so that movement of said movable member will vary the amount of air passing thru said passageway.

2. A device of the class described comprising a wick burner having a relatively small projection thereon and means for enclosing all of said wick except said projection in a housing whereby said projection may act as a pilot burner when the rest of the wick is extinguished.

3. A device of the class described comprising a base, a wick burner and a housing adapted to at least partially enclose said burner, a standard extending upwardly from said base, legs connected with said housing at one end and with said standard at the other, and a pivoted rod having one end adapted to act upon said legs to raise or lower said housing as it is lowered or raised.
